my cso doesnt work

ok im kinda pissed off that some of my cso's work and some dont and some iso's work and some dont. I have 1.5 cause none of them seemed to work on 3.03 OE-C and i never tried it on 3.10 OE-A. is there some settings that im missing to setup in recovery or something?? I went back to 1.5 to try to use my old 0.45 devhook which seemed to work awsome before but it doesnt seem to work now... what can i do!!!

you should never need to use umdgen to make an iso when you dl it it should be a iso or cso file in a zip form. If you construct it in umdgen then it could mess something up try this one if you use a torrent to download. 007 From Russia With Love
